NANNING - China had built and connected 39.1 million kilowatts of offshore wind power to its national grid by the third quarter of 2024, ranking first globally, according to a conference on offshore wind power industrial chain cooperation.

China has formed relatively complete technological and industrial chains of offshore wind power, covering design, manufacturing, construction, operations and maintenance, according to the conference held Saturday in Beihai, South China's Guangxi Zhuang autonomous region.

Participants at the conference discussed issues such as strategic innovation, key offshore wind power technologies, as well as international cooperation on modern offshore wind power industrial chains.

Rich in its offshore wind energy resources, China has seen fast development in the industrial chains. China's installed offshore wind power capacity grew from under 5 million kilowatts in 2018 to 37.7 million kilowatts as of 2023, accounting for 50 percent of the global total.

The localization rate of offshore wind turbines in China has surpassed 90 percent.

In the future, the offshore wind power industry should innovate in its industrial integration models, strengthen core technology research and deepen coordinated industrial development, so as to form internationally competitive industrial clusters, said Shu Yinbiao, an academician of the Chinese Academy of Engineering.

Test Bench for 35 MW Wind Turbines Goes Into Operation in China

Shortly after Dongfang reported that the company produced the world's first 26 MW offshore wind turbine, China's Sany Renewable Energy announced a test rig for turbines of up to 35 MW was put into operation at the firm's wind power testing centre.

Test Bench for 35 MW Wind Turbines Goes Into Operation in China​

October 17, 2024

Shortly after Dongfang reported that the company produced the world’s first 26 MW offshore wind turbine, China’s Sany Renewable Energy announced a test rig for turbines of up to 35 MW was put into operation at the firm’s wind power testing centre.

Sany said that “China’s first and the world’s largest” test bench utilises a 100 per cent domestic supply chain and is capable of simulating the full lifecycle of wind turbines up to 35 MW.

Equipped with six 100-tonne hydraulic cylinders, it applies multi-directional, coordinated loads across six degrees of freedom, allowing for extreme, multi-axis stress testing, according to the company.

With a maximum driving torque of 36 MNm and a bending moment of up to 80 MNm, the test bench accurately simulates complex weather conditions and extreme working environments, withstanding typhoon-level winds, said Sany.

By utilising high-intensity accelerated fatigue tests, it simulates 20 years of wind farm operation in just one year.

The test bench can simultaneously perform functional tests, failure limit verification, and design model validation on the entire turbine and key components such as generators, gearboxes, and main shafts.

In other news from China this week, Dongfang Electric Corporation (DEC) rolled a 26 MW offshore wind turbine off its production line.

A single unit could lead to a 30,000-tonne reduction in coal use and an 80,000-tonne cut in CO2 emissions. According to DEC, the wind turbine is the world’s largest in both capacity and size.

Offshore wind buildout expands

China is set to double its cumulative offshore wind capacity to over 100 gigawatts by 2030 during the 15th Five-Year Plan period (2026-30), pivoting aggressively toward deep-sea development and multi-industry integration to consolidate its position as the undisputed global leader in renewable...

China targets more than 100 GW of offshore wind capacity by 2030

China is set to double its cumulative offshore wind capacity to over 100 gigawatts by 2030 during the 15th Five-Year Plan period (2026-30), pivoting aggressively toward deep-sea development and multi-industry integration to consolidate its position as the undisputed global leader in renewable energy.

This ambitious roadmap marks a crucial transition for the nation's clean energy sector, shifting from nearshore projects to large-scale, deep-water mega-bases. Liang Changxin, a senior official with the National Energy Administration, noted that amid global geopolitical turbulence and shifting energy markets, offshore wind has become a shared international consensus for securing low-carbon transitions.

"China has already transformed from a follower to a global pacesetter," said Liang during a recently held forum in Jiangsu province.

By the end of September 2026, the country's cumulative grid-connected offshore wind capacity exceeded 49.84 million kilowatts, Liang said. For five consecutive years, China has ranked first globally in both newly added and cumulative capacity, accounting for more than half of the world's total.

Generating over 100 billion kilowatt-hours annually, these coastal wind farms have become a vital green power lifeline for China's coastal provinces, he said.

According to Liang, the economic ripple effects are equally immense. The offshore wind industry boasts a long supply chain and high added value, continuously driving related sectors such as steel, machinery, marine engineering, and shipbuilding.

Currently, nearly 20 large-scale offshore wind industrial clusters line China's coastal provinces, generating a total output value hovering at the 1-trillion-yuan ($149 billion) level.

Technological milestones have powerfully underpinned this rapid expansion. China recently completed the installation of a 16-megawatt floating offshore wind platform — the largest single-unit capacity in the world — and operationalized a flexible direct current transmission project boasting the world's highest voltage and largest transmission capacity. Furthermore, Asia's first flexible DC offshore wind project has generated over 10 billion kWh.

Major State-owned enterprises are spearheading this deep-sea march. China Three Gorges Corp has successfully completed eight million-kW-level offshore wind bases, becoming the country's first enterprise to surpass 10 million kW in offshore wind capacity and leading globally for five consecutive years.

"As China accelerates the construction of a new power system, the new energy industry is in a period of deep adjustment," said Liu Weiping, chairman of CTG.

"Pushing into the deep and distant sea will expand new space and provide new opportunities for the industry's development," he said.
